CVE-2021-24976
The Smart SEO Tool WordPress plugin before 3.0.6 does not sanitise and escape the search parameter before outputting it back in an attribute when the TDK optimisation setting is enabled, leading to a Reflected Cross-Site Scripting
Does this matter?
Lower severity and a low EPSS score (0.92%). Track it; it rarely justifies an emergency change on its own.
